ENVELOPE-DELIVERY DEVICE.

Application filed IIEarch'QG, 1922. Serial No. 545,027.

lowing is a specification.-

My invention relates to envelope delivery devices, and an object is to provide a device which will receive envelopes and stack them in vertical piles as they comefrom the printing press. While my device is intended particularly for use in connection with envelopes which have just been printed, it will-be understood that it may be used in connection with other printed matter.

The full objectsand advantages of my invention will appear in connection with the detailed description, and the novel features of my inventive idea will be particularly pointed out in the claims.

In the accompanying drawings which illustrate the applicationof my invention in one form, Fig. 1 is a top plan view of the device. Fi 2 is a fragmentary view taken substantially on the line 2-2 of Fig. 1. Fig. 8 is a perspective view showing the device applied to a printing press. Fig. 4 is a view in section on the line l 1 of Fig. 1. Fig. 5 is a view in central longitudinal section.

In carrying out my invention, Iprovide a device which is adapted to be attached to a printing press adjacent the position at which the printed envelopes are removed from the platen. Since the device may be applied to.

customary and well known printing presses, and since such presses constitute no part of my invention, it is not necessary to illustrate and describe the same in detail. Referring to the construction shown in the drawings, the numeral 10 designates a customary oscillating arm of the press, this arm having attached thereto a horizontal rod 12 which carries gripping fingers 14c which serve to remove the printed matter from the platen. My attachment includes a base member or table 16 which is securedv to the upper portion of the press. Mounted for reciprocating movement on this table is a pusher 18 which has downward projections 20 which slide in longitudinal grooves 22 in the surface of the table. The table is provided with an opening 24 extending longitudinally along its center and the walls which limit this opening are provided with grooves 25 which slidably receive a plate .28 carried by the pusher 18 whereby thelatter is prevented fromlifting-ofl' the table. Tliis-plateand the projections 20 guide the pusher during its reciprocating movements. A.- springtensioned roller 30 is rotatably mounted in side members 32. so as to be located un-derthe rear end ofthetable 16.; Acord s windsupon the rollerBO and is intermediately secured to the plate 28 and then extends forwardly,

passing over a sheave 36 secured in; the-forward end ,of theopening 24; and oversheaves 38 and 10 mounted on a lateral extension 42 secured to'the table. The extreme end of the cord 34 is secured to the oscillating arm 10 previously referred to. Positioned below the front or delivery end of the table is a container il, the front end of which isopen and provided with a retaining plate 46 extending upwardly from the bottom of-the container and adjustably secured thereto bya bolt 16' which is slidable in a'slot 50. V i i The operation and advantages of my invention will be obvious from the foregoing description. 'The envelopes when printed are removed one at a time from the platen by the fingers ll and deposited upon the table 16. This operation is accomplished by rearward movement of the arm 10, and when this arm moves in the opposite direction during its return movement, the cord34 is pulled against the tension exerted by the roller 30 and the pusher 18 is caused to move forwardly and. push the envelope which has just been brought from the platen over into the container'l lso that the printed envelopes are successively stacked therein, as indicated at E in Fig. 5. The plate 46 is adjusted according to the width of the envelopes, so that the latter will be stacked in a neatly arranged pile. The spring tensioned roller 30 causes the corded to be partly wound thereon when the arm 10 moves forwardly so that the pusher is returned in the proper position for engagement back of the envelope 2. An envelope delivery device comprising a table adapted to be attached to a printing press, a pusher slidably mountedon said table, a spring tension roller positioned adjacent said table'and a cord attached to said pusher, one portion of said cord being adapted for winding on said roller and another portion of said cord being adapted to be secured to a moving part of the press whereby said pusher will be caused to recip rocate over said table. 3. An envelope delivery device comprising a tableadapted to be'attached toa'printing press, a pusher slidably mounted on said table, a spring tensioned roller positioned unde'rthe rear end of said table, a cord intermediately attached to said pusher, said cord having its rear portion adapted for winding on said roller and its forward end adapted to be secured to a moving part of said printing press, and a container positioned below the delivery end of said table and into which the envelopes are dropped to form a stack when moved by said pusher.

4. An envelope delivery device comprising a table adapted to be attached to a printing press, a pusher slidably mounted on said table, means for guiding said pusher, a spring tensioned roller positioned under the rear end of said table, a cord intermediatel'y attached to said pusher, said cord having its rear portion adapted for Winding on said roller, sheaves'over which said cord is laterally deflected in order that its forward end may be secured to a moving part of said printingpress, and a container positioned below'the delivery end of said table and into which the envelopes are dropped to form a stack when moved by said pusher.
